Shenandoah (14-1) scored three runs on five hits in the bottom of the first inning to provide starting pitcher Colin Morse with all of the support he would need.
Morse (3-0) ran into a little trouble with two hits and two walks in the second, but the strong offensive support was more than enough against the Mounties (3-9).
The junior right-hander departed after five innings, allowing four runs (three earned) on five hits and five walks. He also struck out five.
A five-run second, on five hits and one walk, turned the contest into a rout. Dan Cameron, Jake Loew, Nick Goode and Dylan Stouffer all had RBIs in the frame with Cameron driving in a pair on a double down the leftfield line.
Eight of the nine starters had at least one hit with Luke Nussman's 4-for-5, two RBI day leading the day. Cameron had three hits in four at-bats and drove in five while Goode had three hits and drove in three runs.
Luke Stultz (1-2) was tagged with the loss after allowing seven runs on eight hits and one walk in 1 1/3 innings of work.
Shenandoah takes to the road on Tuesday for a non-league contest at Dickinson.
